Hi,

I have altitude, density and time data. How can I do line plotting with time sequence, i.e. time, altitude and density in x-, y- and z- axis, respectively (same as one plot attached but without arrows). I don't need contour plot. The density data is different at different times ( I mean sometime less than earlier values). I am using Matlab2015a.

Thank you so much.

Thank you.

I tried all I could, like, plot3,waterfall,line, plot indivual line, etc..but did not get what I want. here is the dendisy data attached.

code for time and altitude;

time=1:11;altitude=80;0.5:115;

I think it is the time series (x-axis) of density with altitude along y-axis.

See if waterfall() meets your needs. Or else plot x vs. y for every y vector, moving it along a little bit each time along the x direction b y adding a tiny bit to the y signal.

It looks cool but problem is that the x-axis is not time. You have plotted x vs y and x is density here (if I am n't wrong). Altitude is also starting from 0 (zero), it should start from 80 km. I need to plot time(in x-axis), altitude (y-axis) and density; I mean time series of altitude vs density profile. I also tried to use "ax.position" after plotting but no success.

So just get rows instead of columns or vice versa, or plot y vs x instead of x vs y. I think you can figure out the adaptations needed since you're a smart engineer. Let me know if you still can't, and what the rows and columns of the array represent and which (rows or columns) is supposed to go along each axis.
